The Global Warming Debate

Jeff Wiita: Nobody is denying that the Earth has warmed up in the past 150 years. The question here is, is it a natural cycle or is it something that is manmade. If you’re going to talk about extreme weather you have to look back at climate history, and we have written history that goes back to the medieval warm period. During the medieval warm period, the Earth was much warmer than it is today. The English grew wine and had vineyards 300 miles further north than today’s limits. The medieval Vikings grew wheat and barley in Greenland -- that is currently land that is currently frozen – obviously you can’t grow wheat and barley on permafrost. There are archaeological grave sites in Greenland where the medieval Vikings buried their dead, and they’re in permafrost. If you look at it, the medieval warm period was obviously warmer than it is today, and any climate scientist or historian will agree with you.

Ken Bradley: There’s been a lot of money spent by people who have an interest in keeping the fossil fuel industry moving
